SPECIFICATION forming part of Letters Patent'No. 415,530, dated November19, 1889.

Application filed October 11, 1886. Serial No. 215,911. (No model.)

To 6056 whom it may concern:

Be it known that I, GODFREY I-I. LASAR, of the city of St. Louis, in theState of Missouri, have invented a certain new and useful Improvement inType Writing Machines, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,forming part of this specification, and in which- Figure 1 is a top viewof myimproved machine. Fig. 2 is a side elevation. Fig. 3 is a verticaltransverse section taken on line 3 3,

Fig. 4 is a vertical longitudinal section taken on line 4 at, Fig. 1,looking in the direction of the arrows. Fig. 5 is a detail view showingthe tumbler-bars which limit or regulate the movement of the key-levers.Fig. 6 is a top view of same. Figs.7 and 8 are enlarged de tail viewsillustrating the escapement and part of the rack. Fig. 9 is a sectiontaken on line 9 9, Fig. 7, looking in the direction of the arrows, thedogs of the rack being in their upper position. Fig. 10 is a similarview taken on line l0 10, Fig. 8, looking in the direction of thearrows, showing the dogs in their lower position.

This invention relates to certain improvements in type-writers; and itconsists in features of novelty hereinafter fully described, and pointedout in the claims.

Referring to the drawings, A represents the base; B, the key-levers; G,the carriage, and D the type-bar frame of the machine. The key-leversare pivoted to the base at one end by a rod or bar B passingtherethrough and supported by standards B secured to the base.

B is the escapcment-frame, pivoted on the rod 13 and having a rod or bar13 at its front end that passes under all the key-levers. The rear endof the frame has a lug B through which passes a pin 13, extendingupwardly from the base A. The pin has a head 13 on its upper end, andbetween the head and the frame is placed a spring B that acts to sustainthe frame in its upper position.

The escapement-frame is provided at the sides with lugs 13 havingrecesses 13 Extending over the lugs and adapted to bear thereon is thespacer-frame B having a finger piece or key B, by which it is depressed.The spacer-frame is supported by a frame 13 (to which it is rigidlysecured,) pivoted on the rod B outside the escapement-frame, andconnected by means of a log 13 with a pin B secured to the base A,having a head B and a spring B between the log and its head. Thespacer-frame "may be secured to its supporting-frame by means of screwsor rivets B The finger-piece of the spacerframe is located at the rearof the bank of keys, so as to be in a more convenient position, andextends entirely across the type-key levers. r

The carriage in this machine is preferably constructed and supported asin my applications Serial No. 215,904 and Serial No. 318,042, andreference is made to those applications for a description of thecarriage shown in this application.

The escapeinent F in this application is made similar to that shown anddescribed in my application Serial No. 318,042, and to that applicationreference is made for an under- 7 standing of this part of the machine;but in this application the fixed dog, that moves in a vertical linewhen the escapement is operated, is held from lateral movement in itsnormal position by a spring G, surrounding the pintle G of the dog. Thepurpose of this spring is to hold the dog from horizontal movement whenin use for spacing and the carriage is advancing, but at the same timepermit of its yielding or being moved horizontally out of engagementwith p the rack to allow the carriage to be moved back for a fresh line,or for other object.

The escapementdogs F in this case are connected by a rod or'bar F to therod B of the frame B so that they are operated each time a key-lever Bor the spacer-frame B is operated. And when it is desired to throw thedogs entirely out of engagement with the rack of the carriage to allowthe carriage to bemoved either back or forth without printing, the dogsare both moved vertically out of engagement with the rack by a key-leverY, having a key Y, the key-lever when depressed coining against aprojection Y on one of the lot lugs B and by depressing the frame Blowers the dogs, as stated.

I represents the type-bars, each bar having an upper and a lowercasetype secured thereto. \Vhen a lower-case letter is to be printed,projections I on the rear ends of the bars come against a plate H andstop the movement of the bars just as the lower-case type I reach theroller of the carriage. If an upper-case letter is to be printed, theplate H is pulled down, so as not to be struck by the projections I, andthen the upper-case type I will be brought over the roller of thecarriage. The plate H is pulled down by being connected to thekey-levers B by rods H. The keylevers B are pivoted to the bar or rod B,pass into the recesses B when depressed, and are provided with afinger-piece B in front of the bank of keys.

The type-bars are thrown forward by rods L, connected thereto at theirupper ends and to blocks L at their lower ends, the block being pivotedin openings in a segment L in the same manner, preferably, as thetype-bars are pivoted to the segment in my application Serial No.215,907, and the blocks are connected to the key-levers B in thisapmentioned.

key-levers the bars are drawn back and the key-levers lifted by springsL, connecting the rods L to the segment L (see Fig. 4,) assisted by theframe B their normal position without their inner ends coming in contactwith and interfering with half of the bars are allowed to recede fartherthan the others, as shown in Fig. 1. This means consists of a ring D,resting upon the frame D and held in place by screws D connecting it toposts D extending upward from the segment L the posts also serving tohold and guide the rods H by having lugs D, through which the rods pass.(See Figs. 1 and 2.) The screws D pass through slots D in the ring D.The ring D has notches D opposite each alternate rod L of the typebars,and the rods that enter these notches carry their type-bars back fartherthan the other type-bars, the rods of all of the alternate type-barscoming against the frame D, beyond which the notches D extend. Thus, allthe alternate rods coming against the same support D, some of thenotches D may be deeper than others without any effect 011 the movementof the type-bars being caused thereby, thus avoiding the necessity ofbeing careful to get all of the notches D the same depth.

When a machine is first put together, care should be takenthat the frameD be adjusted far enough forward for all of the rods L that enter thenotches to come against it; or, in other words, the frame must be placedfar enough forward to be in line with the notch or notches of the leastdepth, and no attention need be paid to the other notches. Theadjustment of the frame is allowed by the slots D through which thescrews D pass, as stated. Only one of the rods L is shown in Fig. 4.

. The type are inked by a movable pad M, located under them when intheir normal position, (see Fig. 4,) and the pad may be moved up againstthe type by a key-lever M, on which it is supported by a link M thekeylever being provided with a key M by depressing which the pad ismoved up against the type. The pad is guided by sleeves M thereon,fitting over rods or pins M on the frame D. (See Figs; 2 and 4.)

\Vhen the type-bars have been moved to bring the type into printingposition, they are struck by a hammer N to produce the printing orimpression. The hammer is pivoted at N to a frame N and is connected byarod or bar N to the inner end N 4 of a lever-frame N pivoted at N tostandards N projecting upward from the baseA of the machine. Secured tothe outer ends of the frame N is a rock-bar N connected by links N to asimilar rock-bar N secured to the base A by arms N by which it issupported. The bar BI is pivoted to the frame N at N and the bar N ispivoted to the arms N at N This pivoting of the bars allows them to beturned from the position shown in Fig. 4

. to the position shown in Fig. 5, and as To allow all the type-bars tocome back to the upper surfaces or faces of the rock-bars are fartherfrom the pivot-points N and N than the inner faces it will be seen thatwhen the rock-bars are turned into the position shown in Fig. 5 (whenthe inner faces will be brought uppermost and the upper faces will beturned outward) there will be a greater distance between the key-leversand the rock-bars than there is when the rockbars are in the positionshown in Fig. 4. The object of this is to permit of a greater movementof the key-levers B when the upper-case type are to be brought intoprinting position. The rock-bar N acts to limit the downward movement ofthekey-levers B, and when in the position shown in Fig. 4 permits thekeys to be moved just far enough to bring the lower-case type intoprinting position. Now, when an upper-case letter is to be printed thekey-levers B are first operated to depress the plate H, (as alreadydescribed,) and as these key-levers are operated the rock-bar N isturned from the position shown in Fig. 4 to the position shown in Fig. 5through means of its being connected by links N to the key-levers B thusallowing the keylevers B to be moved the necessary additional distance.As the rock-bar N is turned the rock-bar N is also turned through meansof the described connection, so that the keylevers B do not come againstthe rock-bar N so soon as when in its other position, thus giving timefor the type-bars to be moved to bring the upper-case type into printingposition before the hammer is operated. IVhen the rock-bars have beenthus moved from the position shown in Fig. 4 to the position shown inFig. 5, they are returned to their normal posit-ion by a spring N coiledaround a pin N on one of the arms N (see Figs. 4 and 6,) the pinentering the rock-bar N and this turning of the rock-bars back elevatesthe key-levers B through means of the connect ing-links N It will beseen that the key-levers B are sustained in normal position by the linksN, blocks N arms N and springs N The carriage-roller is turned for a newline in this application by a lever arrangement, such as is shown in myapplication Serial No. 215,904, and the carriage is run back for a newline by means of a rock-shaft O, journaled in boxes 0, secured to thebase A and connected by means of a rod or pitman O and a crank or leverO to the bell-crank lever 0 that turns the rollers of the carriage, asdescribed in my application Serial No. 215,904. The crank O is securedto the shaft 0, as shown in Figs. 2 and 3, and by rocking the shaft itwill be seen that the carriage will be run back. The shaft is rocked orturned by means of a handle P, pivoted to the shaft at P, and in movingthe carriage back the handle P is moved in a vertical plane in the arcof a circle.

I disclaim any invention in the combination, with the type-bars, ofkey-levers and connections, substantially as described, between thekey-levers and the bars for operating the bars, stop, block, and bars towhich the stop is connected, provided with a key for operating the stop,as shown and described.
